Think at when we create a block step with buttons to choose in the case of a long selection the UI and UX are not really good. So i think that having a dropdown menù with a input text field on tha we can add the options could be really better and more usable from user. To can conect an option (selected by dropdown) with an other block i'd connect the conditional block to can select the next block related to specific option or to entire block step.
