Send real Host header in httpchk requests

Hi, folks!
Is there is a way to send real backend address as a Host header in the httpchk requests? We are currently using HTTP 1.0, but would like to switch to HTTP 1.1 and sending meaningful Host header is a mast in your case. Here is our current backend section of the config:

backend apiservers
  balance                 leastconn
  mode                    http
  option                  httpchk GET /healthz HTTP/1.0\r\nAuthorization:\ Bearer\ SOME_TOKEN_HERE
  http-check              disable-on-404
  http-check              expect rstring ^ok
  server                  core1 core1.cloud:443 ssl check
  server                  core2 core2.cloud:443 ssl check
  server                  core3 core3.cloud:443 ssl check

Options like http-request add-header Host %[src] and http-send-name-header Host in the backend section seem not affect httpchk mechanism. Any ideas?
