Gender and plural entries in glossary

### Describe the problem

In the glossary for my project (multilingual mathematical texts), I would like to be able to record the (grammatical) gender of nouns, as well as their plural forms. That would mean that, when translating strings in other components, the glossary would be more useful in ensuring that the translation is correct.

### Describe the solution you'd like

Some way of recording grammatical gender of entries (since all my entries are nouns) in the glossary. Some way of recording plural forms of nouns as well.

### Describe alternatives you've considered

I currently have a .json file (https://github.com/thosgood/maths-dictionary/blob/master/nouns.json) that I'm trying to "import" into Weblate, and this file records gender of nouns.
