Remapping looping texture inside mogrt based on mogrt duration inside Premiere Pro

Hello ! 

I am building a mogrt for a LT that has a looped texture as a backdrop. LT has protected regions for aniamtion in and animation out. Now, when i import it to Premiere Pro and shorten or extend the mogrt, the outcome is that the looped texture change its speed outside protected region resulting in some visual inconsistency - protected region has a normal texture tempo and unprotected region has either high rate ( short mogrt) or are very slow (longer mogrt) 

Is there a way to make the texture has just one frame rate regardless of how long or short the mogrt will be made inside premiere pro ? 

many thanks !
