Change JTAG Clock. USB-Blaster

Is there a possible to change the JTAG Clock TCK over Quartus? We program over JTAG and have in a chain a delay around a BIT. The problem could be solved with a slower CLOCK of the JTAG.

With USB Blaster, the JTAG clock is fixed to 6 MHz in the CPLD. It can't be programmed. You should be able to change it however by using a different clock oscillator.
