Hi, and Happy new Year!
This is a great idea, although not specific to Fresco as it's more how the Creative Cloud storage system operates (Mobile apps files and clouds saves from desktop all end up in the same place)
Actually you can post your query in the Creative Cloud Service Channel,
https://community.adobe.com/t5/creative-cloud-services/ct-p/ct-cc-services?page=1&sort=latest_replies&lang=all&tabid=all
or go directly to the user voice here:
https://creativecloudassets.uservoice.com/
and ask for a feature added. (You can also do so in the help section of the Fresco app cog wheel on the top right>app setting>help>suggest a feature)
I can clearly see how it could make it easier for everyone, including on the various Creative Cloud apps, including on the phone.
As for Fresco specifically, a prompt to save to a particular folder in Fresco ( as opposite as saving at the root of the Cloud doc section) would be super helpful!
