Thank you for the suggestion.
It is important that nobody thinks there is any hint that I may misuse their money. If there is a substantial amount unused, which will only happen if the Tribunal makes an exceptionally large award in my favour, I must return it even though that might be a bit of a nightmare. I will only do so in easy amounts, though, eg 25%, 30%, 50%, 100%. Any leftovers will go to charity.
