ability to set practice account starting balance

It would be nice to be able to set the balance in my practice account. I think this would be a dashboard change that just let’s me set how much buffer the account has. The size of the account doesn’t matter, what I’m trying to do is practice with certain amounts of buffer. For example, recently silver has been really hot. But it’s a very different market and it’s very speculative recently. So I want to see if I have 50k buffer in my account, can I survive with /SI or do I need to stick with /SIL. I can certainly “build up” the account by just playing something risky and just resetting constantly till you get this buffer, but that’s just a hack and really a waste of my time and your resources.
