User-defined Tasks, please

I'd like more flexibility in categorizing Tasks

My tasks are not classifiable only by "open, closed, mine, today's, tomorrows, next 7 days", etc.

Sometimes I am in Bristol, sometimes I am in London, sometimes in Manila.
I want to meet different people in each place.
I want to be able to create a set of tasks: 'People to meet in London, when I next go there'
I can put the names in a desktop Word document, but I'd rather keep them in Zoho.
How to do it? It would be good to have the ability to create user-defined views in Tasks.

At the moment, my 'to meet in London' tasks are all mixed up with all the others.
There are perhaps workarounds like creating a new field and adding it to the Tasks layout.
But this is not an elegant solution.
These tasks will still stay mixed up with all the others, though no doubt you could use 'sort', to group together names classified as belonging to the category 'people to meet in London'

But I really want to add the Task 'to meet in London' as a custom view to the Home Page.
Without user-defined tasks, that isn't going to happen.

So, please - user-defined Task views, which I can then add as a Component to the Home Page.
