Insert multiple files at one time

I need to add quite a few images to an existing file. I'm on the PAGE tab, using INSERT. I can only do one at a time. Is there a way to do more, using alt, shift etc to select more than one doesn't work. Thanks

Hi this is one of the issues I have with Architect 8. It is ridiculous having to add a long list of documents one item at a time. If you ever find a solution please do post it here as I can't find one
