Can I somehow auto-import boards?

[kxygk]

I'd like to use nullboard "dynamically"/normally locally as well as host a copy on my Github Pages (so that my advisor can monitor my progress)
So I'd like to autoimport a exported-file that's on a path relative to nullboard.html

I'd then locally modify my board as usual and then use the "Export" feature to update my local board file. I could then use git to update it on the remote server (ie. Github)

This is kind of half way between the manual Import/Export and the Auto-Backup features (that requires an "agent" to write to disk)

Maybe this is already possible - but I'm just not sure how to do it.. maybe some magic URL extension?
I'm picturing something like
