Is ther any mean that I can define setup/hold time constraint in constraint folder so that I can use it for similar nets?
There may be many ways to accomplish what you are after. Please contact me offline if you want to discuss your particular situation.

By offline, I meant that you could email me directly so that we wouldn't bore others with the details. You are correct that there is no corresponding ECSet entry for setup/hold values. If what you are concerned with is easing the process of setting the values, you have 2 options. One is to make use of the hierarchy in CM and put the bits in a bus or class (depending on the version you are using) and set the values at the bus or class level and have them propagate down to the bit level. The second option is to make use of the fact that setup/hold are both net and pin properties. You could use your netlist or the property editor to set the values. If you are concerned about specific pin pairs then the pin option might be best here.
You should also be aware of the limitation that a specific pin pair can only have one value. In other words, you can not have different values for the same pin pair depending on which pin/device is driving.
