Bex prompts in WebI

Hello!

Can anyone tell me if it is possible to have prompt in WebI where user can choose more different values?

For example: I created Bex variable (selection options) in some Bex query. This Bex query is the datasource in some WebI document.

And for this variable we have this prompt in WebI, where there is only interval possible.

We are using SAP BOP 4.1 SP4
