Thanks for the suggestion. We actually have a similar request for “Bulk voting” already documented in our backlog, and I’ll add your post to it.
The idea of enabling bulk voting has been discussed a few times on the forum. However, so far, we always have prioritized other improvements to enhance the overall voting experience, such as the “optimistic voting” feature that we proposed last year.
In my personal opinion, while I understand that such a feature would be convenient, I am concerned that it may lead to votes being cast without thoroughly reviewing the content of the proposals. This could potentially compromise the quality and to some extension the security of the voting process. Instead, I believe it would be beneficial to focus on improving the user experience of the neuron following process first.
Nevertheless, only my two cents and not my call anyway 
. Thanks for the feedback, well noted and documented!
