Missing custom sorting capability and some filtering options

I am not able to use this lightroom despite many good features  just beacuse of missing custom sorting option and more filtering options. 

I shoot wedding and events, in which end result of the images has to follow a certain sequence which doesn't neccesarily come with automatic options. 

I can't even filter images of different SNs of a same camera model to edit capture time.

I strongly recommend Adobe team to include these features.

What are your thoughts friends?
