That's my problem also...not enough drawn comb yet. What seemed to work for me last year, and what I plan to do this year, is two-fold. I run 2-story deeps for the brood nest. I have some shallow depth supers with drawn comb, but the rest is foundation.
First, on my deeps, when I reverse this spring, that will give me drawn comb above, for the bees to move into - take empty bottom, put above top deep in which the bees are clustered. I can pull an outside frame of pollen and honey from the now bottom deep, insert in the middle of the now top empty deep. Then I'll replace the full shallow food super back on top. That one or two frames of pollen/honey moved from the now bottom box into the top deep provides a "bridge" of honey and empty comb up to the feed super. The colony should expand up and out as the weather warms and the colony grows. Hopefully that will enable them to maintain contact with their food reserves.
Second, I have a couple of splits I started late in the season. They have only one deep brood box, and a shallow for food. My plan is to install a deep of foundation above the deep brood box. I'll take the two outside frames of pollen and honey from the bottom deep, replace those with foundation. Then I'll put those two frames of pollen and honey in the top deep, in the center with a frame of foundation between them. That will provide space for the bees to move up, as well as the ability to draw foundation. Of course they'll have to be fed before the flow starts.
I'll have to go back into the bottom box later, to move the foundation closer to the brood to encourage them to draw it out.
Will the plan work? Time will tell. But when you don't have enough comb, you gotta do what you can, trying to incorporate the ideas as best you can.
