Map name as save file name

[Whisper]

Hey guys, its me again. (BTW is that forum almost dead? I don't see many new threats; at least in this section)
Well, now I would like to have map name included in save file name. To clarify — not when I pick a save file, but as ins name in the load screen. For example:

1 Sacred Forest               29-04-2020  16:13
2 Temple of Random God 29-04-2020  16:13
3 Test map234finalxx       29-04-2020  16:13

Right now its "Wstaw nazwę lokacji" which basically means "Insert location name". I set this up like that after few hours of futile attempts to make it by myself. Well... my Ruby knowledge is pretty poor, I'm able to modify only simple things so far.



Here is link to project with scripts I'm using.

Any help is really appreciated. I assure you guys that before I'll ask for help I'm spending 4-8 hours trying to do it myself. I don't want you to feel that I'm lazy and abusing your good will...
