There is nothing that prevents you from manually charging cases on your progressive press. Just remove the powder measure and put a funnel in its place and at each stroke of the press manually measure and drop the powder charge into the funnel.
Note that some people believe weighed powder charges yield the most accurate loads and others believe volumetricly meted yield the most accurate.
Manually dropping powder will slow you down some, but you can do it. Just go for it and see if you like it.
