[AMBER] constructing single nucleotides in leap

Is there a standard way to construct single 3' and 5' terminated
nucleotides using Leap? I am studying pKa shifts in RNA and want to use a
reference in solution.

At present I am using the semi-official "protonated_nucleic" residues. Is a
3'/5' residue simply missing from this library but present in standard
FF10? I can imagine assigning the charges by hand to new residue, but that
sounds like 30+ minutes of irritating grunt work.

Regards,
Brian
