I asked, a while ago, whether there could be some sort of 'style' capability in Impict. I know that the capability is now in HelpXplain - but then I asked the obvious question of whether I could import the .ipps into HelpXplain, etc. etc. and the answer was no

For background - we have hundreds of .ipp graphics, and we take full advantage of the ability to use .ipp files directly in H&M projects - it is very valuable to be able to modify callouts (or replace background screenshots) without exiting, creating new graphics, saving them, and coming back!! We regard this as a major H&M feature.
Recently we have started re-issuing our main products with updated look and feel, and so there are lots of .ipp graphics (i.e. screenshots plus callouts) to re-do.
For the new release, we are migrating all our Help files from .chm to your new .exe eBook - (at your suggestion) - we need uniformity and we need to match our new skin/UI. For new subjects we will use HelpXplain and have the benefit of styles/themes - but it leaves the question about the old .ipps.
We need to update all the .ipps with a uniform (new) style for callouts - different font, different colors for outline and background and so on. At the moment we have to redo these individually. Changing the font and colors of callouts is tedious to say the least!
So I am repeating the question (plea?) - can you suggest any way I can get better uniformity across a library of images.
First choice would still be to be able to do a either import .ipps as a graphics type into .xplain files or to do a one-time import of .ipp files into .xplain format - this would also allow us to use these as the basis for many animated tutorials that we are planning.
Alternatively, if there could be some sort of 'styles' or 'theme' capability for the .ipp objects, we could more easily do the editing of existing files and still maintain them as .ipp files.
Any suggestions?
Thanks
