Client-side-resolving environment variables in published desktop/app parameters

Currently, it is already possible to use certain system environment variables within the parameter field when defining a published resource (e.g. %clientname%). This environment variable gets resolved on the remote side (contains the real name of the client).

This request here would like to see the possibility to add client-side resolving environment variables e.g. %%myCustomEnvVar%% to send dynamic content from the client-side over to the remote full desktop or app on start of the session.

This would open much flexibility to solve certain scenarios. --> Citrix can do this and we are using this actively.
