Filtering report embeded in page

Filtering report embeded in page

Right now we are using a page variable to filter a report on a page. However, it being a page variable makes it reset if you go to another report/form, we want the filter to be kept the same. I tried using an application variable according to zoho you can set the value of a variable using button actions in a Stateless form, which is what we use for the user to select the value they want to filter by. So that doesn't work.

Value of variables cannot be modified through scripts in the following workflow actions:
Stateless form - button actions

Using a page variable works perfectly besides this, does anyone have a solution? Thanks! :)
