Is your feature request related to a problem? Please describe.
Sometimes it is useful to turn an existing piece of text on a Canvas into an Object. This is possible! 
. It is not yet possible to turn the same text into a Relation.
Describe the solution you’d like
Show Relations in the “Turn into object” menu (either block level menu or text-quick-menu):
- Select text with keyboard or cursor
- Use the overflow menu from the quick menu
- Use the existing option “Turn into object”
- Search for the Relation (for example “Creation date”)
Describe alternatives you’ve considered
As inline Relations are not yet a thing (see FR) this could currently only be implemented on block level, but once inline Relations are there, this should also be possible on a text level.
Additional context
This might be useful for cases where you have imported/pasted information from an external source as plain text into Anytype. Selecting a piece of text to turn it into a Relation for that Object would be helpful.
