Hi Leon. You can definitely add multiple labels no matter what plan you are using! In any input field that is asking for tags or label selectors you can add multiple name:value pairs by separating them with spaces or semicolons. For example, you can enter “owner:bob; env:production” or “owner:bob env:production”. If you want to verify that the parser is doing what you expect, just click outside of the field and the pairs you’ve added will appear in separate icons underneath. You can also add or remove name:value pairs one a time in this way.
We should probably add a tooltip or help icon to the UI that explains this, so thanks for bringing it up!
