There is no "Decayr" attribute in the ETSAP TIMES model generator. Are you referring to some other modelling system?
If using TIMES, you could use the technology-specific dynamic constraints for bounding the increase/decrease in capacity/activity, and with the general TIMES user constraints you can formulate almost any kinds of constraints for any sets of technologies, including dynamic constraints limiting the increase/decrease in activities, capacities, flows, and investment costs between periods.
Please see the documentation: Part II: Comprehensive Reference Manual
– Section 6.3.39 for technology-specific dynamic bounds on growth/decay
– Section 6.4 for general User Constraints
