hi r66,
What do you mean by 'i have multiple drop down lists that all have to have the same option'. Means for all combo lists have to be same value or any thing.
If your wish is to have the same value in all combo lists. Bind the data source to a drop down list, after that copy the drop down from UI and paste it where ever you want.
If it is not your wish please give indetail.
Hope this will help you.
