C++ Builder. How can I add the TabOrder property myself to those components that do not have it?

Question

C++ / C#

Is this even possible? For example, I have a regular button and an unusual button (third-party, TPngButton)
So, the third-party does not have focusing on the Tab key. How would I attach such a property myself? Where is it prescribed for a regular TButton?
I am writing in C++ Builder 6.
Any ideas and comments on this topic will be welcome.

Question in style: Guys, I bought a car, but it only goes 50 km/h, but the Bugatti is calm and pulls 300 km/h, tell me how to do 300 km/h on my speed.
The only possible solution is inheritance, no more, and it is not known whether it will be enough.
