Set node label in jenkins pipeline

Question

Can I set a label instead of a name for Groovy nodes? We want to define labels outside the script so that we can easily access them from the Jenkins toolbar.

Idea: Instead:

---

Groovy script

node('Slave_1 || Slave_2'){ echo 'Hello world' }

---

We want something like this:

---

Pipeline configuration

Node Label Name:     slaveGroup
Node Label Value:    Slave_1 || Slave_2

Groovy script

node(slaveGroup){echo 'Hello world'}

Or can you use labels that you can set in the sub configuration directly in the Groovy script?
