Multiselect field with tags analogy

Hi I was wondering if it possible to plan in development additional functionality to multiselect field…

It would be great to add functionality that would allow you to insert a list of comma-separated variables and move them to tags if the specified word is in a drop-down list. This would significantly reduce the page content creation.

For example, we have pre-packaged variables for multiselect field
AAA
BBB
CCC
DDD

and a comma list
AAA,BBB,DDD,FFF

When you insert this list the tags will be AAA,BBB,DDD.
FFF will be ignored…
