It is not currently possible. The code to do it is trivial, but nobody has really pushed for it before.
That said I'd probably suggest notations for this, even though 0x40 exists in the standard. 0x40 signatures are a bit of a leftover tail in the standard, and are not well specified (0x40 sigclass - is it a binary signature? a text signature?). Using notations also gives you more flexibility since you can do key=value stuff and specify different variations on timestamp signatures.
