[Lazarus] derived forms and frames

I have been developing programs in Delphi for many years (and even
before in turbo Pascal).
I would like to switch all my programming from Delphi to Lazarus / Free
Now I have encountered a serious issue that I don't know how to deal with.
I have built a complex framework that I use in my programs. This
frameworks includes form templates and frame templates from which I
derive most of the forms of a project. In order to be able to derive a
new form from a form tempate easily with the means of the lazarus IDE,
the form template must be part of the project - I don't see another way
to have a form shown in the menu "file - new".
But in order to make new published properties of the template form
available in the object inspector, the template form must be compiled as
part of a package.
But for good reasons it is strongly disadvised to use the same file in a
package and as part of the project at the same time.
Of course, I could manually modify the source for every new unit that I
create, but that would be rather cumbersome and error prone.
I would like to ask if there is a solution to the problem that I am not
aware of - otherwise I would file a feature request. I feel that the
ability to use forms and frames derived from TForm and TFrame as a base
for new forms is a very important feature to build an efficient
programming framework, and this programming framework should not be
required to be part of every project that uses it. I would suggest a
procedure similar to "register", which should place a menu entry for a
form or a frame from a package into the menu tree "file - new", just
like register places a component into the component palette.
