Since I asked, there has been the development of a way to search for objects on the internet, both in Kstars and in the Scheduler. So now I just type in the name (or copy-paste) and if it is in GSVC, it will be found. Not so far ASASSN-variables, CSS and the like - still needs typing in coordinates (as far as I know).
But: it would be good to hear how you import that CSV-file. I produce csv-files as export from VXS, would be handy to just import them, for variables less easy to find the other way.
