Confirmation dialog in Leave Request

Hi Experts,

My requirement is to display a dialog in Leave Request application (FPM_OVP_COMPONENT, HRESS_A_PTARQ_LEAVREQ_APPL) when the value is selected in a drop down. I will try to make it more clear with the screen shots below:

1. I want to display the dialog box when the 'Type of Leave' is selected and for certain leaves only:

    2. Here are the technical details of the field, and I see the FPM event 'LRF_TYPE_OF_LEAVE_SET()' is assigned to the field:

   3. There's a dialog page already existing in the configuration. Can I use the same page with different messages while opening it to the user?

This configuration using the feeder class 'CL_HRESS_PTARQ_LEAVREQ_GUIBBF', but I do not see any FPM events within this.

Please suggest how can I achieve this?

Thank you,
