Is it possible to make a jumper with MOSFET?
The CD4016 is a CMOS quad bilateral switch. This would work if your signals are between 0 and about 15 V.



Figure 1. Switching a CONTROL pin high connects the associated IN/OUT pins.

Check the series on-resistance of the switch. It may be a couple of hundred ohms and this may affect your circuit. I seem to remember that the CD4066 had a lower on-resistance.
