Sterling Secure Proxy Known host key store configuration to support multiple public keys of a client

In general, Linux/Unix SSH/SFTP clients can support multiple know host keys for the same DNS host and port. When different servers behind a load balancer present different host keys, the client typically stores and validates multiple entries in the known_hosts file without issue.

On similar lines, is there any support in Sterling Secure Proxy (SSP) 6.2.x, or is it on the product roadmap, to allow bundling multiple SSH known host keys for a trading partner into a single known hosts file and uploading that file into the SSH Known Host Key Store?

Specifically, can a Netmap node reference a known host key store entry containing multiple valid host keys (for example RSA-2048, RSA-4096, ECDSA P-256, Ed25519, or old/new keys during rotation) and accept any of those keys during host key verification?
