Workflow: Add additional value on existing property

So you want to add an extra value to a multiselect property. You could create a script to do that for you. The script could retrieve the list of lookups already in that property, add one more item to the list and then save it again.

cool, I'm script-literate - do you have an example script that I could mimic for my needs?

Well, I have a rather complicated 300+ line script that does the above while retrieving lookups from several different sources, checking that they are not already in the list and then saving the new, compiled list into a new property. That is way too complicated for your purpose, it would take some time for me to pick out the relevant parts and create a working sample. But I do believe I posted something of the sorts about a year ago. Perhaps a search might help you find that example. Can't remember the topic from back then though....

Thanks! I have since chatted with another colleague who might be able to create such a script. I'll be sure to share it here once I've confirmed we've got it right
