Multiple profiles and profile folder

Hello all,
I'm using Joplin 2.8.8 and I'm very happy to see multiple profiles support.
Actually I have two portable installations.
I would like to install joplin on desktop (not portable) and set it up with the two existing profiles.
Is there an easy way to do this?
Can I change the profile folder?
I would like to keep the joplin resources on another drive (larger than my laptop SSD disk), so I would like to change the profile folder. Is the "portable" version the only solution?
TIA
tony
