TokenMod API Help- Prevent the rollable table for tokens from returning to index 1

I'm using the TokenMod API script for a game and a player brought up an issue to me that when using the following command as it causes some confusion !token-mod --set currentside|+ Using it with a number sometimes causes the token to loop back from the beginning, and continue moving.  Is there a way to get it to stop when it reaches the final number on the rolling table, instead of looping back and starting over? 

Yup.  From the manual under SideNumber: If you preface the command with a  ? , the index will be bounded to the number of images and not wrap. In the same scenario, this would leave the above token at image 4: !token-mod --set currentside|?+3 In the same scenario, this would leave the above token at image 1: !token-mod --set currentside|?-30
