Could you possibly give a translation to the terms to "bucket" and something about upgrading "UuA"???
Sure - a bucket just means a Selling Class inventory. Inventory on BA is measured from zero to 9, O1 means BA has currently 1 ticket in selling class O. O9 means 9 or potentially more. Another way of expressing this is to say that the O "bucket" has 1 or 9 tickets available. UuA just means Uprade using Avios. In this forum's Dashboard there is a guide to abbreviations and other jargon.
For the first point, clearly the moment has passed, but with this sort of query if you give the exact dates and flights then we can research the options and allow you to make an informed and specific request of the Contact Centre. Or wade your way through ITA Matrix as detailed above. But in essence you probably need to say "please book me on flight n on date x in the N bucket" or "using selling class N" or something similar.
