Can i keep the factor of Scale?

#1
Hi.
I'm Choi in Korea.

When i use the Scale feature,
1. Select entities
2. Base point
3. scale factor
I input it in order, but can i use the scale entered in same scale factor again next time?

If i input 0.5 during the first operation, I hope 0.5 factor will be maintained at the next operation.

Is there a way?

Thank you.
