How can we add bleed valves to the second floor of our baseboard radiant heat system with 34 copper pipes if there aren’t any currently installed?

So, our house has baseboard radiant heat with 3/4 copper pipe. But here’s the thing – there are no bleed valves on the first or second floor. We’ve already tried to bleed the air from the basement, but we can still hear air in the line. Do you happen to know if there’s a way to add bleed valves to the second floor?
None of your radiators have any bleed valves?
To properly address this, you’ll need to individually isolate each radiator and pump fluid through them one by one, ensuring the pump’s full gallons per minute (gpm) is achieved.
Simple. Start by identifying your zone valves, circulators, and shut-off valves (depending on your system type). Some systems have one pump with multiple zone valves, while others have a separate pump for each zone.
Automatic air bleeder valve
Standard air bleeder and expansion tank setup. This setup catches air bubbles and releases them.
Do you have bleeders in your baseboard radiators? If not, you may need to add some tees. Are there ball valves to isolate the zones for a quick purge? Do you have air elimination in the attic? Are there any trash can bleeders off the boiler? How old is your circulator?
