In WTM, how do I find all prepositions without a pronominal suffix?

The closest I've gotten is:

.*@Pp* !*Pp+S[123]*

This finds prepositions without a pronominal suffix. But if there are multiple prepositions in the same verse, some with a pronominal suffix and some without, it will omit that entire verse. For example, I want my search to find the last word of Gen 1:29 (‎ לְאָכְלָֽה), but it doesn't find it because the verse also contains prepositions like ‎ לָכֶ֥ם that have a pronominal suffix.

Thanks for any help!
