How can I use trans_choice with multiple variables?

[lana-k]

I have a message that should be localized. The message has numbers and I want it to use plurals or singulars depending on the numbers. I know that there is trans_choice but my message contains multiple number variables:

"You have selected :n participants for a time slot with :m available spots."

So, it can be:

• plural-plural: "You have selected 5 participants for a time slot with 3 available spots."
• plural-singular: "You have selected 5 participants for a time slot with 1 available spot."
• singular-zero: "You have selected 1 participant for a time slot with no available spots."
• plural-zero: "You have selected 2 participants for a time slot with no available spots."

Is it possible to achieve with one translation key? Or the only way is to have one choice msg for single selected and one choice for multiple selected with 3 options in each of them (plural available, single available, no available)?
