Parametric patterns

Hello,

Is it possible to create a pattern in a part with mulitple distances. For example 6 holes 4 holes equally spaced and the pitch of outer left/right side holes differ from it.I want to use it as driving feature for bolted connection(s).

In attachment (Part1.pdf)l eft/right pitch196mm other holes pitch150 (3x150=450). Length 842 can change as well as the dimensons of pitch and number of holes.

It would help if the parameters can be driven by equation manager (SW2012) instead of Design Table.
