Nope. Thaumcraft is based on progression. You need to delve into area A to start out in B. Node jarring is a reward to progressing, enabling useful deatures down the road, such as wand recharge.
You don't even have to progress very much, you don't even need infusions to move nodes early. A gold capped greatwood scepter and or stave and a little bit of research has you able to move nodes within a couple of hours, probably less.
I actually think there should be a simpler way of nabbing nodes though. Like a portable node jar that would be DEEP in the artifice tree.
You'd build it like normal but if the mod doesn't detect a node in it's structure it will make an empty portable node jar that can be clicked on a node to capture.
Failing that, a mod to the focus of equal trade that lets you build the jar structure around a node with a click so long as the appropriate space is surrounding it and of course the blocks for the jar are in your inventory. Either that or a totally new focus that lets you save a copy of a structure with this function built in.
