Create a template pool to select from on ad-hoc document generation

If I have many templates (in my case 80+) I want to be able and have a template pool / gallery and be able to select the template I want to use in a specific case from a dropdown.

It’d be my responsibility to make sure I have the right placeholders in all templates in order not to break anything.

Right now, working with status column isn’t relevan’t due to the 40 statuses limitation by monday.
And also maintaining versions and updates at this scale is very hard.
