Unfortunately, the drawback of this approach is as follows. We have a service that receives Tally webhooks and updates our users' info based on the poll answers. For 'true/false' information in our system (like 'Do you have a cat?') the service can check the text of the chosen option in Multiselect, like 'Yes' for true and 'No' for false. But our users have distinct languages, so for a concrete poll there would be no 'Yes/No' variants, but their analogues in other languages. A possible approach would be to have all possible variants in our service, but it can be literally any ('Sure', 'Of course', not just 'Yes'). Another possible workaround would be to set a custom tag for Multiselect options (it is already available for fields, known as 'Rename fields'), like 'BOOLEAN-QUESTION-TRUE' and 'BOOLEAN-QUESTION-FALSE', but there is still no ability to do that.
Hey Ilia — thanks a ton for the feature request and for being a Tally user! We love hearing from you. ✌️ As a workaround, you could see if one of our current input blocks can be repurposed to suit this need (i.e. two Multiple choice options): https://tally.so/help/input-blocks#943528e6f66f48ed858812222…
