Custom grid

[jaikoljadoo]

Greetings from India,
I am using Oruxmaps since 2016. Thank you for listening to users and releasing new updates.
My question is regarding creating waypoints.
I have my own grid system (Indian grid) can i put these data to make any waypoint?
I saw there is an option newly added as "+codes". Similarly can you add a field for the EPSG code or Indian grid?
Thanks once again.
