Can you import one field into two fields? (split ISSN into eISSN and ISSN-L?)

Hello all,

Is there a way to split items in one field so they are imported into different fields?

PubMed records give multiple ISSNs. For example:

IS  - 1938-0674 (Electronic)

IS  - 1533-0028 (Linking)

I’d like to import the Linking ISSN into the ISSN field, and put the other ISSNs into Notes.

I can hide the electronic ISSN by using Replace Text from IS  - to (Electronic) with <blank>, but I can’t figure out how to move it to another field.
