Questions

Good morning all,
I am French so excuse my English please. Urzagatherer is fantastic it really is a great tool to sort my collection. Thanks for creating it.
My question is as follows: I collect Magic cards in French and only in French. Some series have only been edited in English (for example). Can I "delete" these series? So that they no longer appear in my Urzagatherer? This way I could close some series and have exact statistics.
Thanks in advance for reading me and thanks again for the work.
