I use some custom agendas for work and some for personal stuff. At the moment I load a huge set of custom agendas in
org-agenda-custom-commands containing all agendas for work and for personal stuff. This clutters up the dispatcher.
When I define two different sets of custom agendas, one for work and one for personal, I can only load and access agendas of one set. But with home office, sometimes I need "work agendas" on my personal computer.
How can I write the configuration, that I can "add" sets of agendas to
org-agenda-custom-commands if necessary, without completely replacing it with one set or the other?
