7/8 signature with alternating beaming possible?

I would like a 7/8 bar that shows beaming as in the screenshot, but where the time signature still shows 7/8, not 3/8+2/4. Is that possible?

Write this in the meter popover:
[3+4]/8

Check out this document to learn more about the popovers:

EDIT: If you don’t want the new meter to show, you can simply hide it from the properties panel

Thanks, and thanks as well for the pdf link, very helpful!
