Cant Modify ALV Toolbar Dropdown Buttons in PERSONAS

Hi,

I have an issue with these four buttons (found in the ALV Toolbar) in Personas. My screen design requires new icons  for the ALV and its butttons..

The first 3 buttons are Filter, Choose Layout and Sumup/Total. Each button will have 2 functions Eg. Filter + Dropdown Menu

The 4th button is a Export. It only has a Dropdown Menu.

Requirement

Need to redesign these 4 buttons with all their functions intact.

Issue Faced in Personas

1) Personas recognises the first 3 button types as a single button.

2) Cant change the icon of these buttons (passing ICON_ID in the element properties)

3) Using a script button with a PUSH feature I can only access the Filter Button but not the dropdown function.

4) When using a script button  with a PUSH feature on the Export_Button it throws an error.

So basically Personas is having trouble identifying with the DROPDOWN feature of these ALV buttons. And secondly Icons cant be changed for these buttons for some reason.

Any input/ideas to modify these buttons would be much appreciated.

Thanks.

Abraham
