However, I find it strange that there is no master security list. I guess it is probably this way for historical reasons, but for those of us migrating from Quicken who have long tranx histories (longer than our brokers are willing store on their OFX servers). We need to import from Quicken as QIF, enter CUSIP and perhaps change currencies (for multi-currency portfolios), then import OFX. 20,30,40 names across multiple accounts (me/wife/kids x IRA/Roth/taxable x different brokers). The work is tedious.
Any suggestions as to a quicker way? Is there anyway to specify CUSIP in QIF? I can handle a text editor.

Failing that, can master security list be implemented? Will we see it in V11 or V12? It is probably a cleaner way in the end, as there will be times where one has to enter prices manually.
Now that Quicken is a monopoly, there will be even less incentive for them to add features. I see lots of unhappy customers like me who are paying for upgrades without getting any new features. That translates to a big potential market for you. But only if migration is relatively painless.
I have a few other minor suggestions I will post separately.
