Reinforce positions

Is it possible to reinforce my position by buying or selling same symbol with different leverage ?
Example : I have 10 ETH already positioned. LONG . And with leverage =5

I want buy others 20 ETHs - LONG with leverage = 15

It’s possible ?

After , How I know the ENTRY PRICE and others data of my secondary position ?

It’s possible to adjust leverage and place another order to adjust current position.

Thank you Dino !

Only one POSITION appear at UI , right ?

And how can I see data of these two or more positions ?

Qtty is de sum of the several positions , right ?

Can I see the entry data of both positions ?

The new or more recent leverage is the used to calculate PNL ?

Wich is the brother API to see these data ?
