How to combine liability coverage for classic car and daily driver?

I currently own a 1990 JDM car. I currently pay $2200 a year on comprehensive coverage as my main vehicle. I am looking to purchase a daily driver to save on mileage, gas, and insurance costs. If I purchase a classic car policy from Hagerty or similar company with actual value comprehensive coverage on it, I am quoted at $90 a month with 100k/300k liability coverage.

I don’t believe I want any collision on a cheap daily driver, as I am looking at a $5k price range, I have my classic as a temp backup, and I am fully medically covered under Tricare.

If I purchase one police under the classic, is there a way to combine liability coverage only to the two cars without significant price increase, so I only have comprehensive on my classic and not on my daily?

When I try to add the other car on online tools, it forces me to do comprehensive on both or just liability on both, with no option to mix.
