[FEATURE] Multiple LINE apps or allow us to send to other chat room per LINE account, not just one

**Is your feature request related to a problem? Please describe.**
When I use the LINE app, it seems that I'm only able to send only one chat room per app/integration/LINE account, for every workflow. Even after logging in again, it will just update the said app.

**Describe the solution you'd like**
How about allow us to either allow creation of multiple LINE apps or allow us to choose other chat rooms, not just the one that we selected when adding the app.

**Do you have a workaround?**
I think you can do this by creating another account on either Pipedream or LINE, but I'd appreciate it if I can do it within a single Pipedream account and a single LINE account.

**Comparable features in other tools?**
IFTTT does it. It lets me choose which chat room to send.

**Additional context**
None.
