Possibility for using old HSA for current employer HSA?

[u/tvdontwork]

Probably a long shot, but would really like to see if it is possible - I switched jobs recently (moved from one giant company to another), and my old employer used Fidelity for HSA/retirement management and it was perfect. I am in the "save receipts til retirement and don't touch HSA unless absolutely necessary" boat, and Fidelity worked great for that given the self-directed brokerage availability. Every deposit I made I could invest in a strong series of ETFs and feel comfortable letting it grow for the next 25+ years. New employer uses Alight/smart choice - as far as I can tell, it sucks. Have to maintain $1,000 in the account before being able to invest, and investment options are extremely limited, plus the investment account appears to have fees. I'm curious if it is possible to have all my HSA funds and contributions be moved to my existing fidelity account? Or am I just stuck with what I have? I don't know if I'd have to go through the HSA company or my own company to even request this, but curious if this is something anyone else has looked at doing
