Programmatically add PID and CAN?

Can I programmatically add to Car Explorer > Library > My Library > + Create (both PID and CAN)? If not, can “Custom Code” power a dashboard widget Field?

As described in my other thread, my vehicle requires extended header, mode, and pid and AutoPi Cloud can’t handle that. The UI prevents me from using the device in any meaningful way. Since PID and CAN power literally everything I need to bypass the standard creation UI.

Checked out the web API and it has the same limitations. Is the web software open source to the point I could make these changes myself?
