Frames in conductor resizing when exporting parts

Good evening,

I am editing an orchestral score. I add 2 vertical frames on the first two pages (resizing each frame to one page). Inside the first frame, I copy an image, that I extend to the the page frame full size. In the second frame and page, I do something similar. And then, on the third page, the music begins, with a frame on top, including title, subtitle and composer's name. I resize the frame and set the text lines apart to le them breathe.

When I export all this work to parts, the frames, the image, the text lose their resizing ! I have to do all these operations manually. Imagine this work over 17 instruments x3 movements... Insane ! Isn't there a way to make sure my first pages settings are transferred to each parts automatically ?

Thanks for your help (and in the file, check the page setting from timpani to the right... I already resized the previous ones...).

Kind regards,
Grégoire
