Monitor multiple switch interfaces instantly - Grafana 12.0.2

I’m using Grafana (12.0.2) with the Zabbix (7.0.13) plugin as a datasource.
I’m monitoring several switches, and each switch has multiple interfaces (with items like “Interface X: Bits received”).
Right now in Grafana, I have to manually add every interface to a panel.

How can I automate this process so Grafana automatically creates a panel (or series) for each interface of a selected host, using variables and repeating panels?

I wish to be able to add all of them into a single time series panel.
Please give me the step-by-step setup for the variables and panels, and include any regex needed to clean the interface names.

This might be considered as a “noob question”, but that would fit the description. Right now I’m adding the interfaces one by one, and since I intend on monitoring a couple more switches, I would like to find a way to facilitate this process.

This is what I got right now:
