Another option would be to temporarily plant multiple plants/divisions in plastic tubs like these, filled with a lightweight medium otherwise they'd be too heavy to lift. You can get many plants into something like this.

If you don't want to go to the expense of buying several tubs and planting medium, daylilies can be dug without washing off the soil and "parked" with rootball intact in plastic grocery bags and be fine for quite some time in the shade. They should be well watered first and need periodic dampening of the root ball. It's easier than potting them. I don't know if there are any rules about garden soil crossing state lines like there is crossing international borders. I've done this method in mid-summer and the plants survived just fine. They would likely need the foliage cutting back to reduce moisture requirements whatever method you use, as kidfishing mentioned.
