I have a client whose pay day ends on Friday and they would like Timesheets Grid to reflect this.  They are running Odoo v12.0 on Odoo.sh and I am having difficulty making this change.  I am currently trying to edit code in src --> enterprise --> addons --> timesheet_grid --> models --> analytic.py.  When I make changes, there does not seem to be any impact.  I am saving the file in Odoo.sh editor, pressing Odoo --> Update current module (which runs odoo-bin -u timesheet_grid --stop-after-init). 

This is a two part question so that I can solve this issue.  One, am I editing the correct file to make this change?  -And two, am I deploying the changes correctly?
