Custom attributes & Custom columns

Hello. I would like to be able to add custom columns and attributes to the resx file. The fact is that I use a custom T4 template to generate the .cs class, and I would like to add a LogLevel attribute to some records so that my T4 generates methods for the logger.
For example, resx can be generated like this:
```xml

Broadcast initialization error

```
It would be nice, for more detailed configuration and generation of .cs, I would like to include some more columns there, so as not to write code manually, but for me the T4 template did it. Thank you in advance.

PS Now I use a crutch and just add the necessary information in the comment, for example, "#loglevel=debug#console=red". I don’t like it, it’s hard to read and understand, but it makes the job easier. It would be very cool to see the individual columns and the information in them.
