multiple elements in parallel

[SK Min]

How can I use multiple multiple parallel elements in the schematic? For 
example, I have 20 mosfets in parallel and the net list would be like below;
MN1 1 2 0 0 N L=0.8U W=20U M=20
20 is too many to be placed in the schematic without using 'M' factor. 
Making M=400U would result in inaccuracy in current mirror or high 
impedance circuits.
