TMs not included in project package

I just hit the same problem as these two questions that have never been answered:

https://community.sdl.com/developers-more/developers/language-developers/f/57/p/7339/42172#pi239031345=1

https://community.sdl.com/developers-more/developers/language-developers/f/57/t/11091

Is SDL aware of this problem and is there any workaround?
I cannot figure out how to include the TMs.
