Need input from generous Pro.

I have used Premiere Pro in an extremely rudimentary way for a decade now. I'm finally taking the time to ask you all the correct way (if possible) to do a few routine things I have to do.

I own and operate Musix4me LLC (Website, YouTube). I create scrolling and page turn follow alongs for music accompaniments. Very simple stuff. There are some things I do all the time that I'm sure I am ignoring a quicker, more efficient way to do.

1.  I create a score for my music and may have 50-100 pages (images) when I export them. I invariably need to resize them when I place them. They will all have the same adjusted dimensions. Question: Is there a way to adjust the size of all of the images at once?

2. I only use one transition (Cross Dissolve). I may have a significant number of transition places to apply it to. Question: Is there a way to "load the cursor" so that I can simply go straight across adding the same transition multiple times? Or, is there a way to select all the transition places and apply Cross Dissolve to all of them at once?

I know these are very basic things, but if you could share you best practice for doing these things, I would appreciate it greatly.

I am using the latest versions of Windows 11 and Premiere Pro.
