I am designing a 4-layer PCB:
Signal
5V
GND
Signal

I am trying to use thru-hole vias to connect from a signal layer to one of the internal layers, for example, from top layer to 5V. How do I do this?
I know I can set start and stop layers in the via properties, but that creates a blind via, which are expensive so I would like to avoid it. Is it even possible to have a thru-hole via only connected at specific layers?

I was planning to just setting start layer as top and stop layer as bottom and just specify the net as one of the internal layers. Does this physically only connect at those layers or is there more work to be done to accomplish this?
 

Provided you have already internal planes defined, you just place a regular via (through all layers) during routing and it connects automatically to the same net plane and keeps isolation to all other net copper features. Or place a via any time later and assign it to the respective net.

If for some specific reason you are intending to avoid connect the power bus at selected layers, could try to insert at the schematic scope, some PCB directives at these nets, however must to somehow separate the nets for instance with jumpers or another trick that allow distinguish them by its name.
