I’ve never had a git account, but I just created one to upvote this per the suggestion. Kinda surprised it only has 19 up-votes, but I don’t know what’s considered a threshold or how upvotes are weighted. I’ll have my wife and dog create a git account too.
This request for internal pads is a subset of a long standing request for complex stackups eg to simplify flexi-rigids
Welcome to the world of software forges 
That is one particular issue and there are at least 4 more; here is one Net ties, star routing and decoupling capacitors as first-level tool (lp:#1571930) (#2018) · Issue · kicad/code/kicad

Net tie on internal layer - Layout - KiCad.info Forums. I am one of many that would <3 a more robust/flexible solution but it takes time, the complex pad stackup is a step in the right direction
