Can ctwm iconmanager display google-chrome titles or ctwm-assigned window labels?

google-chrome shows window titles in tabs, but when minimised it does not
seem to be possible to identify google-chrome windows in the icon-manager
except by remembering the order in which they were created (which is why
NoSortIconManager is crucial for my sanity).

Am I missing some some way to make google-chrome windows have titles (also
used used in iconmanager), or is this just a stupid design flaw in
google-chrome for which there is no user-workaround?

I've tried all the available user settings options that I can find in g-c.

Firefox automatically makes the title of the current tab the window
title and that's what shows in iconmanager. I would prefer to be able to
have fixed window titles (e.g. private, project1, project2, department,
news,...) shown on firefox windows and on iconmanager). I guess I should
post that request to mozilla, unless there's some way ctwm can be made to
give each window a fixed label, shown in titlebar and used in iconmanager.

For information: the machine I am now using (at home, logged in to
departmental machine for email)  has uptime 14 days -- usually hibernated
at night, or when I am out. It has 23 firefox windows, each with multiple
tabs, corresponding to several different research projects and frequently
used general resources.
