Third Time's the Charm: BIG-IP Backups Simplified with iCall

Is there a way to run a TCL script created in the editor from within the iCall script definition. Another way of asking this, is, is there a way to invoke that script as a tmsh command. It seems as though tmsh cli script run scriptname.tcl does not work. I have found myself developing a a script to run in iCall as a normal script but there's a little bit of work to transfer the script. It would be easier to just call it from the iCall script if possible,
