How to stretch MORGT on Premiere pro?

Hello everyone,

i am having a little issue with MORGT, i created a cool text animation in AE and i exported it as a template to use it in PPro.

I wanted to be able to stretch it in PPro, in other words: i may want the text to appear shorter or longer than the original time and of course the protected areas need to stay non touched.
I used a wiggle effect on the text and i want just to make it appear fo more or less seconds but still wiggling like it does in the original template time, thats why i cannot insert frame freeze segments or cut the template in PPro nor change the duration because i will loose the wiggle effect or the protected area timing at the beginning and the end just like you can see in the fotos.

I just want to find a way to stretch it in a way letting the text stay more seconds but maintaining the same wiggle effect the whole duration until the ending protected area comes .

Is there a straight forward way to do it please?

I can afford the MORGT file too if someone can edit it for me, but i really want to learn it for my next editings.

Thankx for your time.
