MIDI Messages Start Option Wanted: Sync Slave Play Disabled

Is it possible to ignore a MIDI Start message? I want to use the BB to play a sequence sent on Channel 10 from a BeatStep Pro without it also playing Part 1 of the current Song in BB.
Maybe something to add in the next firmware update? :rolleyes:
In the meantime I will see if I can get BeatStep Pro to send its MIDI data without sending a Start message.
