We have 2 types of trays 5mm which utilizes one tray slot in the Splice Enclosure and 10 mm tray which utilizes two tray slots.

The way we went about this was by creating a "RESERVED TRAY SLOT" tray in the tray Library and whenever we add 10mm tray, we also add a "RESERVED TRAY SLOT" tray in the following slot.

Can we find solution for this?

ie. gray out the following slot when we add the 10mm tray.
