Anyway to restate theorem in external file?

[thisiscam]

Hi,

Thanks for maintaining this nice package. I was wondering if there's a way to use thm-restate so that the restatement is in a separate file? In particular, is there a way to integrate with the xr package?

A quick brainstorm suggests this is doable. Though It may take me some time to implement and test.

See also this SE question: https://tex.stackexchange.com/questions/333596/restate-theorem-in-separate-file. The solution doesn't seem very ideal to me though (it lets go of thmtools)

New CTAN package reptheorem (https://www.ctan.org/pkg/reptheorem) may help.
