Extending Blockly with new openHAB commands

I have a generic Blockly script that runs when a light group is triggered by a motion sensor. It then waits a certain amount of time to turn off the light or in the case of a retrigger of the motion sensor keep the lights on. I’ve tried to do this with the timers available in the OpenHAB section but that doesn’t work properly as timers (or probably the event context) is lost when a different light group is triggered.

I’m now using the common blocks from this community marketplace post: Collection of common blocks. Basically the timer block that keeps the triggering event context. That block actually works great and allows me to create the desired automation.

Is it possible to include the common blocks (or at least the specific timer one that keeps the event context) into the main OpenHAB section? It’s to avoid that I’m dependent on an ‘external’ block instead of what is available in OpenHAB out of the box. Thanks for considering!
