Automatically Attach Custom Forms to Expenses

[#1]

We can auto-attach custom forms to Projects and Tasks, but not expenses.

We have custom Invoice and Receipt data we want provided with each expense, but this requires the user to make the effort to add the form rather than the system automating it.

This would be such a time saver!

[#3]

I could use this functionality too!

[#4]

I'm wondering if we could use Fusion to make this happen? Has anyone used Fusion to attach custom forms to Portfolio, Program or Expenses?
