Health Savings Plan HSA Company Contribution Recommendation

Our company now wants to add an employer paid contribution to employee enrolled HSAs.  Of course the preference is to also tier this with a max contribution and it's not necessaryily a percentage or dollar match so I already have approval to maintain the employee level amounts manually at the PR14 level.  Anyway, do others here generally just approach this by adding a company paid deduction code to the BN15 HSA plan or do you prefer to set this up as a separate BN15 plan?  I've already created and tested a new PR05 deduction code added to the existing BN15 employee plan and that seems to work.  Just don't want to box us into a corner if others here recommend a different approach.
