Automatic build .deb packages?

How did the question: I recently realized that the packages for Ubuntu are going to support old machines. After rebuild kernel with optimization for my CPU I noticed that the computer started to run very noticeably faster.


So while I have no desire to go to Ghent, despite the fact that I basically get along well with Linux.

So, I have no desire at all to rebuild all packages when you update, just some that I use very often (chromium or transmission, for example).

Experts, attention a question: is there a tool that would work according to the following algorithm:


1) I mark the packets which would have followed.

2) once synaptic find any updates of any of these packages, it downloads not the package itself, and its sources.

3) After receiving the package, the package must be automatically collected in the deb package with the given optimizations

4) Package is installed so that it is visible synaptic, and waiting for updates, then the procedure is repeated


So, such a tool exists?
