How do i link my playstation account to steam account without losing anything?

ive had my playstation war thunder account for around 6 years now, have many tech trees researched, or im deep into them, and ive spent an ungodly amount of money in this account and do not want to lose it. but now that im playing on pc, i want to be able to have all the features that pc users have. like being able to access marketplace, or being able to buy whatever premium, because for some reason playstation accounts only have a handful of premiums to look at. For example, my friend has the option to buy the A10A premium, i dont. He has the option to buy the SU-30MK, i dont. its torture and i really want to be able to get these planes, especially considering the sale is coming up soon.
And to add salt to the wound, i looked at gaijins support website for account transfers, and the same shit comes up thats been coming up for YEARS, which is this:

Please note! Due to a high volume of inquiries, the procedure for transferring console accounts has been temporarily suspended. An announcement regarding the resumption of the procedure will be made separately on our official forum

And its been like this since as long as when i got my first pc, which was years ago… and i done some digging into account transfers like that, and if i recall correctly, they said when i transfer accounts, i dont get access to any premiums at all, only golden eagles… this has to be a joke… that means the only thing id be able to buy is some shitty bushes and some silver lions, oh and to speed up the research points for tanks or planes that already takes WAY TOO LONG. even with a premium jet, its taken me YEARS to reach top tier, and i havent even researched the last vehicle on said tech tree.

so please, if anyone knows anything, or even if gaijin sees this for all i know, tell me or help me with it.
i cant even receive or send gifts to my friends cuz im on console, this whole console thing is a piss take.
