take out securities from loans when paying it back

[meiru]

would be nice, if we could take out the securities from the loans when we pay it back... so, e.g. I've a 60M loan and 3 aircrafts as security... when I pay back 40M of it, I would like to take out 1 of those 3 aircrafts, because otherwise the bank has a 70M security for 20M loan

an other option would be, that you could "renegotiate" the loan, so that I can take out those 40M again with the same securitys in the future

Unnecessary. Just take out singular loans for every security asset. If you take out a single loan against 3 different assets, you made a mistake and you have to face the consequences.
