Configuring .ssh/config to forward host aliases to a remote host?

We use jump hosts to access our hardware. These hosts are short-lived (less than a day), and are different every time they're generated. I would like to be able to configure my local .ssh/config file to have the aliases to my real hardware, and be able to forward those aliases to my jump host.
I had tried the following command but it failed:
ssh <jumphost> -t bash -ci ssh <hostalias>
Are there any options that I can try?
jumphost don't mind hand typing, because it is changes so frequently. I just would like a way to automate the process of jumping to that host, and then to the real hardware from there.

In your .ssh/config:
Host farsidehost
HostName acutalremotehostname.example.com
ProxyJump bastionhost.example.com
You can then execute ssh farsidehost.
If as your updates tell, the name of the jumphost changes frequently, you can instead specify it on the commandline:
$ ssh -J jumphostoftheday.example.com actualremotehostname.example.com
If there is some way to procedurally find the name of the jumphost, this can be automated:
$ ssh -J $( determine_jump_host ) actualremotehostname.example.com

Hey thanks, I should make it more clear in my question; our jump hosts are different every time (they only live for a few hours at a time).
