I tried something like that:

    <!-- Sample Analysis Projects List View -->
    <record id="view_sample_analysis_project_list" model="ir.ui.view">
        <field name="name">project.project.translab.list</field>
        <field name="model">project.project</field>
        <field name="arch" type="xml">
            <list string="Projects" multi_edit="1" create="false">
                <field name="project_code" />
                <field name="name" readonly="true"/>
                <field name="user_id" />
                <field name="partner_id" />
                <field name="customer_project_manager_id" />
                <field name="customer_reference" readonly="true"/>
                <field name="progress_analysis" widget="progressbar"/>
            </list>
            <header>
                <button name="%(action_sample_analysis_project_wizard)d"
                    type="action"
                    string="New sample analysis project"
                    class="oe_highlight"/>
            </header>
        </field>
    </record>

But that gives me:

odoo.tools.convert.ParseError: while parsing /mnt/odoo-translab/translab_samples/views/sample_analysis_project_views.xml:87
Error while validating view near:

<data __validate__="1"><list string="Projects" multi_edit="1" create="false">
                <field name="project_code"/>
                <field name="name" readonly="true"/>
                <field name="user_id"/>

The root node of a list view should be a <list>, not a <data>

View error context:

Hi,

You can hide the default “New” button and replace it with your own button that opens the wizard.

<record id="view_project_tree_inherit" model="ir.ui.view">

    <field name="name">project.project.tree.inherit</field>

    <field name="model">project.project</field>

    <field name="inherit_id" ref="project.view_project_tree"/>

    <field name="arch" type="xml">

        <!-- Hide default "New" button -->

        <xpath expr="//tree" position="attributes">

            <attribute name="create">false</attribute>

        </xpath>

        <!-- Add custom button to trigger wizard -->

        <xpath expr="//tree" position="after">

            <header>

                <button name="%(your_wizard_action)d"

                        type="action"

                        string="New"

                        class="oe_highlight"/>

            </header>

        </xpath>

    </field>

</record>

Hope it helps.
