Lengthening charging time of a capacitor
I say "leaking" the capacitor because a lot of time, the capacitor wold be directly grounded and the redirected current would not be used anywhere, so it might as well be flowed back to ground. Hence, it''s like placing a resistor in parallel with the capacitor
Interval time dependent wake-up effect of HfZrO ferroelectric capacitor ...
In this work, the wake-up effect of Hf-based ferroelectric memories has been studied as a reliability concern, and related mechanisms have been proposed. By changing different waveforms, it is found that the wake-up behavior strongly depends on the interval time, and the memory window increases faster with the shorter interval time. Moreover, this …
Why does capacitance affect the charging time of a capacitor?
Second what makes a capacitor "bigger" (in the sense of more capacity). If you take an electron away from a positive charge, it develops a voltage. The more the charges are separated, the higher the voltage is. So the voltage per charge of a capacitor goes up as the plates get more separate*, and the capacitance goes down.

Tips and Techniques for Capacitor Testing
However, a capacitor is much simpler than a battery, because it can''t produce new electrons—it only stores them. Inside the capacitor, the terminals connect to two metal plates separated by a non-conducting substance known as a dielectric. A capacitor''s storage potential, or capacitance, is measured in farads. A one-farad (1F) …

Lengthening charging time of a capacitor
A more complicated solution is to create a constant current sink (and this is not a simple resistor as per your shunt resistor idea). The sink would be in parallel with the capacitor and basically this diverts current away from the capacitor making the net current into the capacitor smaller and hence increase the charge time.
Understanding Capacitor Charge Time: Calculation and
Capacitor charging time can be defined as the time taken to charge the capacitor, through the resistor, from an initial charge level of zero voltage to 63.2% of the DC voltage applied or to discharge the capacitor through the same resistor to approximately 36.8% of its final charge voltage.
