Airdrop Mission

I’m experimenting with airdrops using the HISO BK4 on a Matrice 4 and the HISO Bk3 on a Mavic 3T.

My plan is to use it to mark locations on the ground via Waypoint Mission. Since they are RTK units, the locations are very accurate. The drop arm trigger is fully controlled within Pilot 2 via PSDK, so it adds a payload (you see the camera payload + the airdrop mechanism payload). I can assign the trigger to a button on the conroller. My question is - Can I assing that action via Litchi? Anyone done anything like this?

I’d say unlikely.
If the goal is to plan waypoint flights with Litchi Hub, you could plan in Litchi Hub and export to KMZ and import the KMZ in DJI Pilot 2
