Switch to include PALO.EL with Paste Data Function

To make use of the new flexible cube layout functionality PALO.EL subfunctions inside the PALO.DATA are needed. Inserting the PALO.DATA with the "Paste Data Function" dialogue thus requires to manually edit this pasted function for each dimension of the cube. It would be nice to have a checkbox or similar in the "Paste Data Function" dialogue to call for automatically inserted PALO.EL subfunctions (either with the default element as chosen by "guess arguments" or the default read element if specified, not sure which would be better).
