Multi Item Sort

[EagleMB]

I have a custom field that I use to identify whether a song charted, and which chart it was on. For example, if a song is on the Top 40 chart this month, there would be a tag that states "Top 40 (201904)." If the same song made the Country chart next month, the tag would state "Country (201905); Top 40 (201904)."

I would like for MM to automatically create a playlist for each chart that is sorted from newest to oldest. I know how to make an automatic playlist, and to have it sort by a column. The problem is that any song that made more than one chart will not be properly sorted for one of the playlists. Is there a way to make MM sort by the second item in a multi item field. For example, if the custom field stated "Country (201905); Top 40 (201904)," is there a way to make the colum sort as if "Top 40" was listed first?

Custom fields are not not multi-value fields (like Genre), thus this is not possible.
