CDB and PDB with different character set

I need to create 1 CDB and 2 PDBs - Oracle version 19.3

RE: both pdbs have different NLS_CHRACTERSET requirements.

1. the larger(24 TB) PDB needs to have NLS_CHRACTERSET =WE8MSWIN1252
2. the smaller(1.2 TB) PDB needs to have NLS_CHRACTERSET =AL32UTF16

Using DBCA, I created the CDB with 1 PDB with NLS_CHRACTERSET =WE8MSWIN1252. Next, when I try to use DBCA to Manage Pluggable databases / Create a Pluggable database, it does not give me an option to create the small pdb with NLS_CHRACTERSET =AL32UTF16

How can I accomplish this ?

thank you
