Flexible String Filtering in PALO.DFILTER (Multi-Select or Regex)

Currently, in the PALO.DFILTER function, filtering based on a string value is limited to only one specific value at a time (e.g., = "Comment a"). This limitation restricts the ability to filter multiple values or patterns dynamically.

It would be useful to enhance PALO.DFILTER by allowing:

• Multiple string values to be selected at once (e.g., = "Comment a" | "Comment b")

• Regular expressions (Regex) for more flexible filtering (e.g., = "Comment .*" for all comments)

This would eliminate the need for multiple filtering statements.
