Test means of coefficients for two groups

[Student24]

Hi

is there a way in Eviews to test the means of regression coefficients of several different groups which are determined by different dummy variables?
E.g.
Regression 1 with sample: dummy_variable_a=1
Regression 2 with sample: dummy_variable_b=1
->test the 2 coefficient of the two regressions for statistically significantly different means

thanks a lot!
