PA52.1 versus PA52.5 field lookup

Sorry folks this apears to be my week for questions that have never been brought up to me before in the 7 years I have been working with Lawson...

The field lookup on the PA52.1 is a button with V on it.  It takes us to HRSC.1 (select control) which has no search function.  But on the PA52.5 the field lookup button is the drill around button that takes us to the searchable list for that particular code/field. 

Are there any changes we can make to the PA52.1 to allow for the drill around look up rather than the select control lookup (which is basically useless to us)?
