Is your feature request related to a problem? Please describe.
Certain situations make building a proper ramrod awkward and impractical.

Describe the solution you'd like
Suppose there were a hand-held ramrod--a device that you could right-click on a munition with to gradually push it, one block at a time.
Maybe it can't push more than two munitions at once, so it only works for the smallest possible cannons, but it can be used in situations where a "proper" ramrod would be harder to use, such as with a small cannon that was field-assembled.

Describe alternatives you've considered
This may also work as a creative-only tool, for testing smaller/early-tech cannon without the lengthy, awkward rotation away from the ramrod. Ideally, the hand ramrod would function as described above in survival, and push any number of munitions in creative.
