Is there a way to autosave blueprints/changes instantly?

Is there a way to instantly and automatically save ANY change I do in the editor to problems when the editor is crashing?

I already set my autosave feature so it saves every 1m, but it doesn’t seem to do what I want.

I use source control, so I basically don’t need the save feature, I just want the changes to be applied instantly.

My guess is I’ll have to create my own plugin?

Unfortunately no. The auto-save is the only option and I think as you already discovered, 1 minute is the most frequent save interval. If your editor is crashing that frequently though, you might want to look into sorting that out, rather than a band-aid solution like having it save every second.
