Certificates of Recommendations are very much appreciated for those few people lucky enough to get 3 lines in Wondrous Tails, as it essentially allows them to choose their prize by using a Gold/Silver certificate.

Are there any chances that the 1 and 2 line rewards also receive their own commendation certificates so we can choose our rewards from those reward tiers as well?
example:
Line 1 gives Jade/Amber certificates.
Line 2 gives Garnet/Peridot certificates.

If so, can the commendations be upgradable?
So that way people who have NEVER gotten 3 lines can over time eventually get something from it?
example:
20 Jade certificates = 1 Garnet certificate (Line 1 certificate-> Line 2 certificate).
20 Garnet certificates = 1 Silver certificate. (Line 2 certificate-> Line 3 certificate).
