Importing sessions with unencrypted passwords

Hi. I have collected a bunch of database credentials in a text file (copied manually from our hosters admin interface for further processing) and wanted to import those into HeidiSQL. Therfor I created some sessions, exported thosr and intended to use that as a template. But this resulted in encrypted passwords in that export and the ones I have collected are not.

Is there some setting to import settings with unencrypted passwords? Or, alternatively, is there a way to encrypt the passwords in my text file?

I'm talking 120+ databases but I'll only have to do this once, new ones I will add as they come. Any advice how to do this preferrably without creating each session by hand would be great :)
