There is not, however in your case why not just create a virtual device with on/off buttons (default) and add the following to the very top of your script:
If hs.devicevalueEx(xxxx) = 100 then exit sub
When the new device is 'on', the script is disabled.
If hs.devicevalueEx(xxxx) = 100 then exit sub
When the new device is 'on', the script is disabled.
