Can I have more than one Personal 401K accounts for the same S Corp?

I plan on contributing personal 401K deductions to a Roth 401K and the company match to a tax deferred account. Problem is my preferred brokerage (for a variety of reasons) does not offer the Roth option. Can I open two accounts - one at TDAmeritrade (for the Roth option) and one at Fidelity (my preferred brokerage) for the tax deferred, company match contributions - for the same S corp? Effectively, there will be two administrators..



Thanks!
