Does AGIC support the equivalent of 'configuration-snippet'

[zhoucengchao]

Hi developers,

Does AGIC support the equivalent of nginx.ingress.kubernetes.io/configuration-snippet? We are migrating Ngnix to AGIC and would like to achieve:

(1) path-based routing &
(2) hostname rewrite.

For (1), we don't find a matching annotiation.
For (2), appgw.ingress.kubernetes.io/backend-hostname: seems similar, but does it support RegularExpression as below?

Thank you!
