EventSearch on strings and fill data until next occurrence

Hi,

is there any kind of EventSearch for text data?

I have a channel group which contains sequencer commands. 

I need to search for "SET:ColorScreen:ALL" and sort values of a current channel to them. 

The sequencer writes the timestamp only for the time a sequence command is given. 

The current path's frequency is 1Hz.

So the amount of values isnt't matching and I would only need the values until the "SET:ColorScreen:ALL" command occurs again.

Is there a simple solution to do this?

Regards,

Thorsten
