can i have a multiselect field on transaction line

AI generated answer (using internal Slack threads):

Based on the conversations, it seems that creating a multiselect field on a transaction line might not be directly possible. One user suggested creating a multiselect field sourcing from an item and defaulting it with a search, but they were unsure if defaulting works with multiselect fields. However, custom transaction line fields can be updated via CSV for most transactions, but not via the Mass Update function as it only works for header fields. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
