Yes, in MEC XII, there is a section on Piedmont, County of (p. 197-204; corresponding coin types #168-173) ruled by the Angevin kings of Sicily/Naples (and counts of Provence) who used the Cuneo mint:
House of Anjou, Counts of Piedmont
Charles I (1259-1276)
Charles II (1305-1309)
Robert the Wise (1309-1343)
Joanna I (1343-1382)
… followed by a section called Piedmont, Princes of Savoy-Achaia (p. 205-220, corresponding coin types #174-187) who used the mints Turin, Pinerolo and Moncalieri:
House of Savoy-Achaia, Lords of Piedmont
Filippo I (1295-1334)
Giacomo (1334-1360, 1363-1367)
Filippo II (1367-1368)
Amedeo (1368-1402)
Ludovico (1402-1418)
By the early 1400s, all these places passed into the hands of the House of Savoy, which we already have as an issuer.
I don't think we will ever have more than a handful of coins under either set of ruling authorities, so I would propose we combine them as an issuer “Piedmont, County and Lordship of”
