Unable to print legal form from 2 different trays

Hi Experts,

We have a requirement to print a legal form first page from Tray 3 of Xerox Nuvera printer(Post script 3), which is pre printed legal paper and from second page onwards print yellow legal paper from tray 4. 

When we checked Adobe LiveCycle ES4 * Printer tray selection link then got to know that 'Designer provides duplicates of common paper types for Letter and Legal paper sizes, specifically to accommodate paper tray selection" but not able to see any duplicate of Legal paper size in ES4. 

Please provide your valuable inputs.
