might be better to put that big shape on a background page and reference it on foreground pages
home==>design==> lower right of page ==> page proprieties
stencil
- create background shape: if you really want to do it this, keep group
- asterisks means you have made changes to this given stencil but have not saved it
right clik ==> save or save as
- to add to stencil....should be just drag over....try it with a simple square
you need to right click stencil and make sure its set to editable
(later you can right click the square in stencil and delete it from stencil)
next ...try putting a small image and a square as a group....drag over
I have saved images to stencil (not 2MB though)...so that works.
I am on visio teams 365...there are other issues with visio 365....but not in this area
