Automatically selecting tags based on tags in another field?

Hi. I’m a non-developer. I have a table that has two multi-select fields. I want Airtable to find records that are tagged A, B, C or D in the first column, and automatically select the WINTER tag in the second field (WINTER is one out of 5 choices in that multi-select field).

Can anyone help me with this? I can “Find records,” but I’m lost after that.
