Random channel selection

Question

Is there a way to select a randomly selected group of channels from a larger group?? 
 For example, I have a group of channels (1-50). I want to select 10 channels, randomly, from 1-50. I don't want to divide 1-50 into random groups of 10 channels, I want 10 randomly picked channels. 
 Is there a way to do this?? 
 I'm running an Eos Ti with 2.4.1 
 Thanks 
 Jeff

kinda (it's macroable though). the only way i can think of is this: 
Chan 1 thru 50 Offset Random Record Group 99 Enter 
Group 99 Offset 5 Enter 
 
there are two drawbacks: the recording of the dummy group in between and that you need to do some math for the second offset. Offset 5 means every 5th channel. so to get to 5 you need to divide the total number of channels by the numbers you want to get: 50 / 10 = 5.
