Is there a way to control Date Axis Formatting in the XY Chart Component?

Hi all-

We have an XY chart that has dates on the X axis (it's reporting results as a function of time for certain measurements). This is going to be a GxP report and thus we need to format the date string to meet internal requirements, namely dd-MMM-yyyy hh:mm.

The problem is the tickmark label format for the chart is limited to only selections that are disallowed by the consumers of this report (see below). How do we add our own custom formats to this drop-down for this chart type? (The DateSetFormat function obviously doesn't work to control this format, and trying to cast the date to a string before the reporting component breaks the charting.)

Thank you!

Marty
