Hey Guys,

I'd like to do something that probably isn't possible but I was directed here from the generic help site so here it goes.

I have a custom Multi Select Picklist with values that are populated from a Global Set. What I would like to do is be able to populate the MSP on the Account and Contact Layouts with extra (already defined) entries when uploading new data with the Import Wizard.

e.g. If we met someone at a tradeshow, entered their data in March and then met them again at a different tradeshow in September, when I upload the new CSV with the new tradeshow picklist value the old one doesn't get overwritten but the new one is added into the field.

I hope that makes sense and, as a fun added caveat, I have absolutely no programming/developing experience so if it is possible please explain it to me like I'm five.

Thanks!
