Family vs Individual HSA’s

Have had a HSA qualifying health insurance the past two years and maxed out family contribution evenly split between my wife’s HSA and mine. Should I continue to contribute 50% in each HSA or can I put it all in one account up to the family max? Employer does not contribute to the HSA so I typically front load the entire amount in January. Wasn’t sure if it’d be easier to just put it all into one account? Appreciate any insight
