Yes you can! To do this:
Go to Short Codes and click Add short codes!
Select which short code option (from *10 to *99) you would like to have this under and then select 'Change the active call route on a number' under the 'Command' drop down menu!
You then select which number and which routes you would like the short code to affect.
Once you have done that, repeat Step 1, making another short code to turn the route back to its previous state!
