[keycloak-user] Keycloak RestAPI to Assign Multiple Groups

Hi, We are planning to assign multiple groups to a single user via a REST API call but it seems like keycloak does not currently an API for multiple groups assignment to users. As per keycloak API documentation, it is only possible to assign a single groups to a user in each API call. Does Keycloak support OneUser-to-MultipleGroups API? Thanks, Moe Doutaghy
