Unconnected via pads on inner layers

I would very much like to use JLCPCBs via-in-pad technology in some projects, but via-in -pad is only really useful when you can build via stacks that don't have copper pads on every layer. Unfortunately, EasyEDA doesn't allow this. Best is buried or blind vias which will leave space for traces on remaining layers, but since JLCPCB can't offer that, second best is a through via where unconnected pads on inner layers can be removed from the via stack. This allows more room for traces/planes on inner layers  since they would only need clearance to the hole and not to the annular pad. A function that would allow me to remove unconnected pads from selected vias would be much appreciated. A completely manual function would be OK for my purposes, for instance selecting one or more vias and choosing which of the inner layers should have pads through a set of check boxes. Regards, Jonas

This is absolutely necessary function!  Blinded and buried vias do price of pcb to 2x. And as You right say, not all pcb manufacturers offer this. This way will add possibility to increase routing area in inner layers, do not made problems to pcb manufacturers, and have zero affect to price. I think, good decision is:  assign property to vias - auto remove inner-layer copper, if no connections in this layer. I.e. when we put trace to vias, this automatically add copper. If this property is off, manually remove/adding of copper is available. Regards,   Albert.
